Tenant information This Open-source Intelligence (OSINT) tool will extract openly available information for the given tenant. The tool is using APIs mentioned in my previous blog post and in MS Graph API documentation. Domain details is returned only for the 20 first domains. For complete recon information, please use AADInternals PowerShell module. Note: Username requests are now throttled! This service is not meant for monitoring users 🤷‍♂️ Note: CBA status is valid ONLY if email of an existing user is given.
